Panel-mount construction suits it for distribution boards and motor control center feeder sections. Panel mount format — no DIN rail adapter required. The breaker bolts directly to a backplate or mounting pan, which is typical for MCCB installations where the frame must be rigidly fixed. Verify cutout dimensions against the existing panel layout before specifying; the XT1H frame shares its footprint with the XT1N series, so a panel prepped for a 90 A variant will accept this 100 A unit without rework. ## Peer comparison: XT1NU3090AFF000XXX The closest functional sibling is the XT1NU3090AFF000XXX, rated 90 A instead of 100 A. Both are 3-pole panel-mount MCCBs in the same XT1 frame. The 100 A unit provides 10 A more headroom on the same physical footprint — useful if the connected load is at or near 90 A and you want margin without upsizing the enclosure. No wiring or bus-bar changes needed if swapping between the two.","metaTitle":"ABB XT1HU3100AFF000XXX MCCB, 100 A, 3-Pole, 65 kA at 480 V","metaDescription":"ABB XT1HU3100AFF000XXX molded case circuit breaker, 100 A, 3-pole, 65 kA interrupting at 480 VAC.
